Is there a difference in diameter between the gti6 exhaust and the 1.8?
Just wondering as I'm getting my new exhaust made next month and I think they will want to use the cup off the end of the cat but I think they are different sizes

I'm tempted to say no, as from what I gather the exhaust is very similar on the XSi and GTi-6 and the 2.0 Cabby, it's just that the CAT is different between them. I'll have a look around and see if I can find something more concrete
No!! everyone knows 1.8's are lightweights in consumption of fluids can't get the gasses out quick enough and end up throwing all the fuel they have just drank back out the inlet, ha ha
I know the cats are different. Gti one is shorter I believe. I'm pretty sure the gti exhaust is 2.5" but I haven't got a bloody clue what the 1.8 is lol. Hopefully the same!

Haha yeah I know there a different length. The 1.8 manifold is utter shite and might as well just be 1 hole in the block lol.
I'm going to guess the diameter is the same because I Know the backboxes are all interchangeable and I highly doubt there is a step down/up in the pipe somewhere.

Because I won't get time to get under there lol.
All I need to know is if the cup at the end of the cat where it meets the manifold is the same size on the 1.8 as it is the gti
Now that I think about it, it has to be because tom306xs had his converted no troubles!
